Firebase for Unity sample app crashes with: Could not find class 'com.google.android.gms.common.api.PendingResult'

I'm trying to run the Firebase sample authentication app for Unity (from here), but the app crashes during initialization.

Here's the crash log:

It looks like you're missing the Play Services Base AAR which contains PendingResult, which may mean you're missing other Android dependencies for the SDK as well.

You should see an AAR like the following in your Assets folder in your project when you select Android as the target platform: * Assets/Plugins/Android/play-services-base-10.0.1.aar

This contains the PendingResult class...

$ unzip Plugins/Android/play-services-base-10.0.1.aar classes.jar
  Archive:  Plugins/Android/play-services-base-10.0.1.aar
  inflating: classes.jar      
$ unzip -l classes.jar  | grep /PendingResult\.class
  1762  11-22-16 22:25 com/google/android/gms/common/api/PendingResult.class

There could be a couple of things that may be wrong in your project:

  • You have the Android Resolver disabled (enable it via the Assets -> Play Services Resolver -> Android Resolver -> Settings menu item)
  • You have a mismatched mix of Android AARs in your project. Delete all .aars under Assets/Plugins/Android/ and allow the Android Resolver to pull the latest set.
